From Catastrophe to Escape: A Bourdieusian Analysis of Personal Debt in The Netherlands
Sociology Compass, Volume 20, Issue 6, June 2026.ABSTRACT This paper examines how individuals experience and respond to personal debt, arguing that debt is not merely a financial problem but a systemic issue that affects social relationships, moral worth, and health. Drawing on online forum posts, and grounded in Bourdieu's theory of capital, the paper introduces an expanded framework of ‘assets’ and

Product differentiation in the fruit industry: Lessons from trademarked apples
Agribusiness, Volume 42, Issue 1, Page 148-174, Winter 2026.Abstract We derive price premiums for patented or trademarked apple varieties, also known as “club apples,” compared to open‐variety apples. We use an expansive retail scanner dataset, along with unique data on apple taste characteristics, to estimate monthly club apple premiums for 2008–2018.

Normalized solutions of the critical Schrödinger–Bopp–Podolsky system with logarithmic nonlinearity
Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.Abstract In this paper, we study the following critical Schrödinger–Bopp–Podolsky system driven by the p$p$‐Laplace operator and a logarithmic nonlinearity: −Δpu+V(εx)|u|p−2u+κϕu=λ|u|p−2u+ϑ|u|p−2ulog|u|p+|u|p*−2uinR3,−Δϕ+a2Δ2ϕ=4π2u2inR3.$$\begin{equation*} {\begin{cases} -\Delta _p u+\mathcal {V}(\varepsilon x)|u|^{p-2}u+\kappa \phi u=\lambda |u|^{p-2 ...

Multiple homoclinic solutions for a class of nonhomogeneous Hamiltonian systems
Boundary Value Problems, 2018 By introducing a new superquadratic condition, we obtain the existence of two nontrivial homoclinic solutions for a class of perturbed second order Hamiltonian systems which are obtained by the mountain pass theorem and Ekeland’s variational principle.

Identification of random coefficient latent utility models
Quantitative Economics, Volume 16, Issue 4, Page 1223-1265, November 2025.This paper provides nonparametric identification results for random coefficient distributions in perturbed utility models. We cover discrete choice and models of multiple purchases. We establish identification using variation in mean quantities. The results apply even when an analyst observes only aggregate demands but not whether goods are chosen ...

Unified gross substitutes and inverse isotonicity for equilibrium problems
Theoretical Economics, Volume 20, Issue 3, Page 941-971, July 2025.We introduce a notion of substitutability for correspondences and establish a monotone comparative static result. More precisely, we introduce the notions of unified gross substitutes and nonreversingness and show that if Q:P⇉Q is a supply correspondence defined on a set of prices P, which is a sublattice of RN, and Q satisfies these two properties ...

Pontryagin's maximum principle for constrained impulsive control problems
, 2020 Necessary conditions in the form of Pontryagin's maximum principle are derived for impulsive control problems with mixed constraints. A new mathematical concept of impulsive control is introduced as a requirement for the consistency of the impulsive ...

Boundary Value ProblemsBy using the well-known mountain-pass theorem and Ekeland’s variational principle, we prove that there exist at least two fully nontrivial solutions for a ( p , q ) $(p,q)$ -Kirchhoff elliptic system with the Dirichlet boundary conditions and ...
